Factual, the open database company, closed a $25 million series A financing, led by Andreessen Horowitz and Index Ventures. VCs Ben Horowitz of AH and Danny Rimer of Index will be joining Factual’s board.

Ron Conway’s SV Angel and former Hollywood agent Michael Ovitz also invested, as did some of the previous angels who put in about $2 million earlier this year (only half of which was previously disclosed).

“The company has very significant aspirations,” says Rimer,” what they are seeking to do is extremely ambitious. We believe they will need a lot of funding.”
